After a cool spring kept Greenland’s massive ice sheet mostly solid, a (comparatively) warm late June and early July have turned half the ice sheet’s surface into liquid, well outside the range of normal for this time of year. Despite the ice sheet’s remote location, its slushy fingers reach across the globe, influencing sea levels and how fast the Gulf Stream current moves. As temperatures rise, its influence could grow larger as major summer melt events become regular occurrence.

Instead, they talk about how the annual temperature departs from an average, or baseline. They call these departures "anomalies.
" They do this because temperature anomalies are more consistent in an area than absolute temperatures are. For example, the absolute temperature atop the Empire State Building may be different by several degrees than the absolute temperature at New York’s LaGuardia Airport. But the differences from their own averages are likely to be about the same.

Watch California Dry Up Right Before Your Eyes In 6 Jaw-Dropping GIFs. “This is a big deal,” California Governor Jerry Brown said at a ceremony Tuesday as he signed into law a trio of bills regulating, for the first time, the state’s groundwater use.

As of Thursday, almost 60 percent of the state is facing “exceptional drought,” the most severe level of dryness measured by the U.S. Drought Monitor. But if you’re not living in a community dependent on bottled water rations, farming land that’s projected to lose $800 million in crop revenue or watching raging wildfires ravage your drought-parched town, the historic California drought may still feel like little more than a headline.

To fully grasp how desperate California is for relief, we’ve created six before-and-after GIFs that will show you how badly the drought has dehydrated the state in just the last three years. The Green Bridge passes over full water levels near Bidwell Marina on July 20, 2011, in Oroville, California, and much lower levels on Aug. 19, 2014. Also on HuffPost: Getty Images.
